The R3 that made Corie feel like a different person.
Corie dealt with jaw clenching, grinding and broken, groggy sleep. She started wearing the Reviv R3 at night. A few weeks in, she sleeps through, breathes through her nose instead of her mouth, and says her stress is down.

The R3, the flat-plane guard behind her nights
Worn while you sleep
Overnight, plus a few daytime hours if you want to move faster. No routine to learn.
Gentle, steady pressure
The flat-plane design supports the jaw without locking your bite, so it can settle where it should.
Ready out of the case
Premium soft silicone, food-grade tested. No boiling, no moulding. Backed by a 1-year warranty.
How did the R3 help Corie?
The three changes she talks about most. Her experience, not a promise.
Sleeps through the night
She used to wake up groggy and short on sleep. With her jaw in a better position at night, that changed. "I'm actually sleeping through the night, and I'm not as groggy in the morning."
Nose breathing, no more popping
She was a mouth sleeper with a clicking jaw. Both eased once she started wearing it. "I used to be a mouth sleeper. Now I breathe through my nose, and the popping is gone."
Calmer, higher HRV
She tracks her recovery, and says her numbers moved along with how she feels. "My HRV has gone up, my stress is going down. I feel like a different person."
Three steps. All of them easy.
Take it out of the box and wash it
Wear it to sleep and 2–3 hours during the day
Wash it and let it dry
Confused about size? Measure your width.
One measurement decides it: the width across your back molars.
Width · molar to molar
| Size | Width, molar to molar |
|---|---|
| Medium | 50 mm or less |
| Large | 51 to 56 mm |
| XL | 57 mm or more |
Tips: use a crisp, firm apple, make sure your teeth are clean and dry, press down evenly, and measure carefully in millimetres. No apple? Cut a piece of cardboard to the shape of your upper arch, or measure the width of a current retainer.
Consistency is the whole game
- Weeks 1-2: the adjustment phase. A little soreness or extra saliva is normal, your soft tissue is adapting, not a sign anything's wrong.
- Build up gradually: shorter daytime sessions first, then overnights. Ease off for a bit if it ever gets sharp.
- Over the weeks: the changes Corie talks about, better sleep and nose breathing, come from wearing it consistently. As she puts it, the first night you'll want to pull it out and that's completely normal.
What people say about the R3
Questions, answered
How should I start? ›
Wearing it: the standard pattern is overnight plus 2 to 3 hours during the day. Build up gradually with shorter daytime intervals first. The early phase is the hardest and gets much easier after a few weeks.
Early discomfort: sore teeth, achy gums and extra saliva in the first weeks are the soft tissue adjusting, not a problem. Take breaks if it gets sharp, don't push through pain.
Faster results: consistency first, then simple stretches like Bite and Hold alongside the guard.
How does sizing work? ›
Width matters most. Measure the outer edges of your upper molars at their widest point, shown in this size guide video.
Medium (46mm) fits teens and smaller mouths, Large (53.6mm) fits most adults, and XL (59.6mm) is for larger mouths.
Why does it work? ›
Think of the soft tissue over the skull like a balloon. Grinding your teeth down deflates it over time, what we tend to call "aging." Adding height back with gentle, consistent pressure runs the same physics in reverse.
How many people have done this? ›
Over 30,000 people have started using Reviv appliances and this method.
What is it made of, and what's included? ›
Premium soft silicone, food-grade tested. Your order is the R3 in your chosen size and colour, with its storage case and instructions, backed by a 1-year warranty.
